To all whom it may concern: 1

Be it known that I, RICHARD THURWALD \VoooHnAn, a citizen of the United States,

residing at St. Paul, in the county of Rainsey and State of Minnesota (whose postofiice address is Oakland Park), have invented a new and useful Combined Ford Primer and Carburetor Control, of which the following is a specification.

My invention relates to improvements in a combined Ford primer and carburetor control, the purposes of which are (1) to eliminate'the necessity for the person operating a Ford car, in order to accomplish an adjustment of the carburetor so as to increase or diminish the consumption of gasoline, of groping around under the instrument board and to locate on the dash the arm of the small rod which controls the needle valve of the carburetor, so that the carburetor may be easily adjusted; (2) to ,enable the Ford operator to adjust the carburetor by turning the button on the instrument'board, ordinarily at the end of the rod used for priming purposes, either to the ri ht or left in controlling the needle valve o the carburetor and effecting an adjustment without impairing its use for priming purposes; (3) to enable the Ford operator by pulling-out on said button to accomplish priming without interfering with the carburetor adjustment, so that by one medium of control,'either the adjustment or primin of the carburetor may be accomplished; 4;) to create this combined.

control by a mechanism so designed and" constructed as to avoid rattle or noise when the Ford car in which it'is installed is in motionor operation, by virtue of close titting and semi-rigid parts; (5) to provide the mechanism affording said combined conanother rod for, or altering the height of,

said rod ,so that said combined primer and carburetor control may be installed without loss of time and without the necessity for making alterations in or substitutions for any of the mechanism of this character with which, a Ford car is ordinarily equipped when marketed or changing the position thereof as originally installed; and (6) to provide a fork at the arid of the rod extending. from the cross bar on top of the needle valve of the carburetor which will fit into said cross bar in such a way as to be practically noiseless and rattle proof and so as to insure an efficient and certain connection with said cross bar at all times when the mechanism is in use or operation either for priming or adjustment purposes. I attain these objects by the mechanism illustrated in the accompanying drawings in which Figure 1 illustrates the position and gen eral outline of the Ford equipment for priming purposes, together with the attachments and innovations herein described which combine to create a Ford primer and carburetor control through one medium of operation; Figure 2 presents a general outline of the fork which fits into the cross bar on top of the needle valve of the carburetor; Fig. 3 is a detail view of the casting 3,

bell crank 4, and the connection between the rod 2 and rod 6. Fig. 4 is'also a detail view showing the position of the casting on the rod reversed. Fig. 5 is a detail view showing the casting in a position in which it extends downwardly from the rod, and also, in dotted lines, in a position in which the casting is reversed and extends upwardly from the rod.

Similar numerals refer to similar parts throughout the several views.

In my invention the rod 2 which runs from the instrument board through the dash, which ordinarily connects with the bell crank 4 meets the rod 6 which attaches to the cross bar 8 on top of the needle valve 10 of the carburetor 11. At the junction of these two rods 2 and 6 the end of each rod is equipped with a fork and by means of a cube casting 5 to which both these rods are joined,

a universal joint' is formed permitting a rotary motion to the right or left. Thus by turning the button 1 on the instrument board at the head of the rod 2 the needle valve 10 of the carburetor 11 may be turned either to the right or left, so as to increase or diminish the consumption of gasoline as may be required.

The rod 2 which runs from the instrument board through the dash to the universal joint is inserted through a casting 3 equipped with an arm 14 at each end, each arm being provided with ahole 15 to accomi rod 2 and bell crank 4:, the priming process modate said rod 2. With the exception of the two small arms 14, equipped with said holes 15 through which said rod 2 runs, the body of this casting 3 practically rests parallel with said rod 2, one end of said casting abutting the base of the fork at the joint end of the rod 2, and being held in a semirigid position by this means and by connection with the upper arm of the bell crank 4-. The body of this casting 3 is equipped with a rectangular slot or hole 13, a hole 12 being drilled through either side of the body of the casting 3 so that the upper arm of the bell crank 4- may be inserted into the said rectangular slot or hole 13 in the body of said casting 3 and a connection made by means of a cotter pin or small bolt with nut. The two arms 14 through which the rod 2 runs, extend from the body, of said casting 3 at such an angle that when the casting 3 is placed on said rod 2-and is in position to accommodate the upper arm of the bell crank 4, the two said arms 14 tend downward from rod 2 as shown in Fig. 3 and when the position of the casting 3 is re versed, end for end, on said rod 2 the said arms 14: tend upward, as shown in Fig. 4:. Thus if the height of the rod 6 extending from the cross bar 8 on top of the needle valve 10 of the carburetor 11 necessitates it, the casting 3 may be placed on said rod 2 so that the two arms 14 tend downward and the body of the casting 3 at a lower elevation is in a position (Fig. 3) where an easy connection may be made with the upper arm of the bell crank 4; or if the height of said rod 6 extending from thecross bar 8 on top of the needle valve 10 of the carburetor necessitates it, the casting 3 may be placed on the rod 2 so that the two arms 14 tend up- Ward from rod 2 as shown in Fig. 4, at-

taining a higher elevation for the body of the casting simply by reversing the position of said casting 3, end for end, on the rod 2. Thus the elevation of the body of the casting 3 may be raised or lowered approximately three-quarters of an inch so as to overcome the difierence in the height of the rod 6 and so as to adjust the position of the body of the casting to permit a connection with the upper arm of the bell crank 4- regardless of the height of the rod 6. By way When the casting is thus attached to the for priming the top of rod 6 swings to follow the movement of rod 2.

The fork 7 (shown by separate drawing as Figure 2) equipped with two pins or arms 16 which insert into the cross bar 8 on the top of the needle valve 10 of the carburetor 11 is especially designed and constructed so as to be noiseless and rattle proof and so as to permit suflicient play upward and downward when the mechanism is in use or operation. Thus when the button 1 is pulled outward on the instrument board for the purpose of priming, the fork 7 will be raised accordingly but on account of its design and construction at no time is the connection with the cross bar 8 on top of the needle valve 10 of the carburetor 11 in jeopardy of dislocation and at all times its posi tion is such as to insure efficiency in use and operation for the purpose of carburetor adjustment.

My invention, by these instrumentalities, enables the Ford operator by pulling on the button 1 on the instrument board, or by turning the same, as the case may be, to either prime or adjust the carburetor convenliently and through one medium of contro I am aware that prior to my invention mechanisms have been evolved with a combined primer and carburetor control in view. I therefore do not claim such a combination in its entirety, but I do claim 1. The combination of an automobile and an engine, of a carburetor for theengine, an air valve and a fuel regulating valve in said carburetor, a single operating lever adapted to operate both of said valves simultaneously or to operate either valve independently, a member pivotally connected to said lever near one end and provided with separated forwardly extendingpoints at its opposite end adapted to cooperate with the fuel valve to actuate the same upon a rotation of the lever, a casting having a body portion and offset arms extending at right angles thereto provided with apertures receiving said lever by means of which the casting is attached to the lever, said casting having an elongated slot in the body thereof intermediate its ends, a bell crank lever projecting in said slot. and pivotally connected to said body intermediate the ends of the slot therein, and a connection between said bell crank lever and the carburetor air valve.

2. The combination with a Carburetor for an internal combustion engine having an air valve, and an adjustable fuel regulating valve, of operating means for said valves comprising a lever mounted for a reciprocat-' ing and a rotating movement, a member pivotally connected to the outer end of said lever and projecting downwardly therefrom, said member being formed with a pair of vertical pin portions co-operating with a part carried by said needle valve, a casting having a body portion formed with ofi-set arms extending at right angles thereto and having apertures passing through said arms to receive said lever and support the casting thereon, the body of the casting being provid'ed'with an elongated slot, a bell crank having one lever entering said slot and pivotally connected to the casting, a. connection between the other arm of said bell crank lever and said air controlling valve whereby said air valve is operated'independently of the gas controlling valve upon a reciprocation of the operating lever.
